So how can a great system solve less than great recordings

Yes, it was $13K, but the improvement in SQ with the Lyra Atlas SL makes ALL my record collection great. By pulling out so much information out of the groves, I love every LP. Sure, the rest of my front end is a match but a world class cartridge has brought a world class sound.
Now playing one of my two Better Records. Yes, it is a big step up.
OK, they are worth it. Now more than ever! Goes from the sound of humans to the sound of G-d. A religious experience.
But I still look forward to every “regular” record.

Lyra, a 13k cartridge, impressive. I suspect turntable kinda nice too.

Introducing my Woodsong Garrard 301 inspired me to upgrade every other component. It may not be the best but it has a drive and life-like sound that is addictive. Especially now with the Lyra, Triplanar arm and Atma-Sphere MP-1. The $28K MP-1 is among the only uber preamp that was designed to be full featured with phono stage dedicated to the ultimate vinyl playback.
With my AGD Audion mono blocks and Tetra 606 speakers, even with formerly poor recordings, I am in Audio nervana.

Everything starts with the source material. Anything after the source material is just masking shortcomings in the original material. While some equipment will help with the overall sound, I think you know how important the source material is. I haven't read all of the posts, but I'm sure people have given SOME good advice!

re: "It would pay to do your "homework" as to what recordings sound best for each title you want in your collection".

Very good idea-- not so easy to put into practice!

I've given up on S. Hoffman forums as one never knows what sort of system participants have or what they consider to be good sound. 

I followed some recommendations based on their "shoot-outs" and was disappointed. 

Really, the only truly reliable source of "recommendation" is one's own ears, listening to one's own system.
